Trade Costs, CO2, and the Environment

چکیده
This paper quantifies how international trade affects CO2 emissions and analyzes the welfare consequences of regulating the CO2 emissions from shipping. To this end the paper describes a model of trade and the environment, compiles new data on the CO2 emissions from shipping, and estimates key parameters using panel data regressions. Results show that the benefits of international trade exceed trade’s environmental costs due to CO2 emissions by two orders of magnitude. While proposed regional carbon taxes on the CO2 emissions from shipping would increase global welfare and increase the implementing region’s GDP, they would also harm poor countries.

Trade Openness and CO2 Emissions in Iran, 1971-2008
The increase of greenhouse gases (GHG) in which CO2 emissions constitute the principal component, is of major environmental problems of all societies. Economic growth impels intensive use of resources and as a result, more residues and wastes thrown in the nature that could lead to environmental degradation. This article tries to trace the eventual relationship between trade openness and enviro...
متن کاملOPTIMAL DESIGN OF NON-PRISMATIC REINFORCED CONCRETE BOX GIRDER BRIDGE: MINIMIZATION OF THE COST AND CO2 EMISSION
This paper presents a computational framework for optimal design of non-prismatic reinforced concrete box girder bridges. The variables include the geometry of the cross section, tapered length, concrete strength and reinforcement of box girders and slabs. These are obtained by the enhanced colliding bodies optimization algorithm to optimizing the cost and again CO2 emission. Loading and design...
متن کاملTrade , CO 2 , and the Environment ( Job Market Paper )
This paper puts the gains from trade and the environmental costs of trade on the same theoretical and empirical footing in order to provide a more complete measure of trade’s welfare effects. To undertake this analysis, the paper describes a model of trade and the environment, compiles new data on the CO2 emissions from intranational and international shipping, and estimates the model’s key par...
متن کاملModeling of solid waste collection and transportation in metropolitan areas using WAGS model: implication of CO2 emission and external costs
Annually more than 80% of the overall budget of the uran solid waste management system in Iran is allotted to collection and transportation of the solid wastes. The main objective of the current study is to evaluate the external costs associated with solid waste collection, transfer, and transportation in Tehran for the period of 2018 to 2032 based on the current situation. Waste guidance syste...
متن کاملThe Effects of Economic, Financial and Political Developments on Iran’s CO2 Emissions
This study examines dynamic interrelationships and causality relationships among CO2 emissions, economic, political and financial variables over the period of 1971-2011 for the case of Iran as one of the top CO2 emitting countries in the world. The results of ARDL and Johansen cointegration approaches confirm the existence of long run relationship among CO2 emissions, energy consumption, GDP, f...
